Ekaterina Roskova

Ekaterina Roskova is played by Alexandra Serova. She is a secondary 'antagonist' in the later seasons of Mabel.

Season Six
Aconite appears first in Primogeniture. She speaks about how no member of the Underhill is happy to see Anna or Mabel. As the season goes on, it is revealed that she believes herself wholeheartedly to be the daughter of the King; however, she is mistaken. She was born in Russia to a political dissident father who died when she was a teenager under mysterious circumstances; she was then taken to the United States-- Massachusetts-- to a boarding school called St. Olga's. When she was 17, she was taken and tortured by Aurora Silver, referred to as Subject 6163 during the experiments. She succeeds in contacting some form of god after being abused for an unknown length of time. After making contact, she dies and ends up in the Underhill, suffering from amnesia. After seeing the King, she assumes he is her father.

At some point after this, she challenges Anna's right to the throne.

After the Girls With Subzero Chill jog her memory, she drops her claim and apparently finds loyalty to Anna.
